Abstract:
PCT No. PCT/SE96/00913 Sec. 371 Date Apr. 10, 1998 Sec. 102(e) Date Apr. 10, 1998 PCT Filed Jul. 4, 1996 PCT Pub. No. WO97/02929 PCT Pub. Date Jan. 30, 1997A vibration-damped, machine driven tool includes a machine housing, a drive mechanism housed in the housing and operable to drive a tool projecting out from the housing, a carrier device which forms a cradle in which the machine housing is suspended, and a vibration damper coupling the carrier device to the machine housing. The machine housing and the tool are subjectable to an appropriately directed tool-feeding force via the carrier device so as to cause the tool to work on an outer workpiece. When the tool is at work, the drive mechanism generates vibrations. In order to reduce the vibrations, the vibration damper includes at least two pairs of leaf spring bridges which are fixedly mounted in abutment with the machine housing and with the cradle formed by the carrier device, and which are mutually spaced apart in a longitudinal direction of the cradle.
